Through analysis of the experimental data about ultrapotassic rocks, typeI ultrapotassic rocks came from the source region of phlogopite harzburgite that had undergone metasomatism of fluid enriched in silica and potassium; while the source region of typeⅢ potassicultrapotassic volcanics is carbonated peridotite mantle bearing potassic amphibole.

综合超钾质岩石的实验资料，可知区内I型超钾质岩的源区以富硅、富钾流体交代形成的金云母方辉橄榄岩为主；Ⅲ型钾质超钾质岩浆源区则以斜辉橄榄岩地幔为主。

In the middle later period of diagenesis, the starting resistance increases, the fluid is not able to flow, the viscous resistance is equal to zero, the ultra-pressure value is equal to starting resistance.

在成岩作用的早期阶段，泥质岩层启动阻力较小，流体可以流动，流体超压由粘滞阻力和启动阻力两部分组成，当成岩作用进入到中－晚期以后，泥质岩层启动阻力增大，流体不能流动，粘滞阻力近似等于零，超压值等于启动阻力值。

The authors believe that the diversification of rock zonation and lithology of these high pressure rocks can be attributed to the metasomatism that took place between deep melt and ultrabasic rocks in the subduction zone, and thus propose a hypothesis of subduction melt metasomatism to explain jadeite formation.

笔者认为俯冲带中形成的深部熔体与超基性岩之间的交代变质是导致岩石分带和岩性多样化的根本原因，提出了俯冲带熔体交代成因说，认为俯冲带、深部流体和超基性岩体是形成翡翠及其过渡品种的3个必要条件，并因此指出在人工合成过程中引入流体相很可能是降低实验条件的苛刻程度、从而合成出真正具有商业意义的翡翠的途径。

One of the essential factors of micronization by RESS is that the solubility of the solute in a supercritical fluid should be as big as possible. So it is important to choose a feasible SCF.

RESS法制备超细微粒的关键因素之一是需要微粒化的物质在超临界流体中的溶解度尽可能的大，因此选用合适的超临界流体是非常重要的。

For example Helium, which we typically engage in its gaseous form. It liquefies at about ten degrees Fahrenheit above absolute zero, and turns superfluid six degrees colder.

用氦举例，我们通常利用的都氦的气态方式，它的液态方式只比绝对零度高华氏10度，如里再低六度，它就会转化为超流体。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
